Python Forum

What are my best bets for an interpreter? I am just starting with Python through Udacity. I have tried Skulpt but have problems with it.

Skulpt is an online implementation of python. You can install python and run its interpreter directly on your computer.

I am running linux, not windows. I have pip installed but for some reason setuptools will not install. I can rn it again and post the error.

in that case you already have. Just type python in the terminal

ptpython and ipython are good.
I use mostly ptpython,look at features here.

or preferably, python3

This is the same problem I am having with ipython. Here is a screen shot

add sudo
sudo pip install ptpython

EDIT:
I didnt even know there were these custom interpreters. Guess thats shows how much i use them directly.

Install it locally as user:

pip install setuptools ptpython --user # for Python 2.7
pip3 install ptpython --user # for Python 3

The switch --user will install the packages into your local user directory (~/.local/) and does not affect your system wide installation.
At some point you'll have a virtual environment for your Python installation.

getting closer, I now have Python 3 >>>, I would like to get ptpython working. here is what I get:

skipperdan@HP-Compaq ~ $ ptpython
